Y doped BaZrO3 is a promising cermet hydrogen separation membrane material. The conductivity of BaZrO3 ceramics depends on the concentration of their oxygen vacancies. In this study, BaZrO3 ceramics doped with In and Pr were prepared by citrate sol-gel combustion method. The effects of doping on ceramic phase structure, oxygen vacancies and micromorphology were studied by XRD, Raman spectroscopy, XPS and SEM techniques. The conductivity, hydrogen permeability and stability of BaZr0.7Y0.2In0.1O3−δ(BZYI), BaZr0.7Y0.2Pr0.1O3−δ(BZYP) ceramics were tested. After doping, The conductivity of BaZr0.7Y0.2In0.1O3−δ(BZYI) is the largest, reaching 9.98×10− 3 S·cm− 1. The hydrogen permeation fluxes of BZYI and BZYP samples were observed to reach 3.50×10− 9 mol•cm− 2•s− 1 and 2.60×10− 9 mol•cm− 2•s− 1, respectively, upon the introduction of water vapor during the purge test conducted at 900℃. Subsequently, the samples underwent treatment in boiling water and a 100% CO2 atmosphere at 900℃ for 3 hours. XRD, Raman spectroscopy, and SEM analyses revealed the absence of any heterophase, thus indicating the excellent stability of the sample
